WHAT IS THE AIR QUALITY INDEX?

The Air Quality Index (AQI) is a measure used by environmental agencies and other public bodies around the world to measure how clean the air is.

The lower the index is, the better the quality of the air.

The AQI provides a number which is easy to compare between different pollutants, locations, and time periods.

Exactly how this score is categorised varies from country to country, but each category in the AQI corresponds to a different level of health risk.

The daily results of the index are used to convey to the public an estimate of air pollution level.
